1、自动生成build.sbt文件
$sbt
>set name := "anjsoft" （:= 表示 sbt.Setting["name"]="anjsoft"）
>session save
2、
ModuleID = groupId % artifact % version % configuration
"org.specs2" %% "specs2" % "1.6.1"
% "test" 返回的类型为 ModuleID ,查更多关于依赖库的方法到 http://harrah.github.io/xsbt/latest/api/#sbt.ModuleID
3、所有增加到lib目录的jar文件被加到classpath中，在 compile ,test, run, console...可用
4、
libraryDependencies += groupID % artifactID % revision
% configuration （+= 看到加号 就到示左边是 Seq[] ,具休这里是 Seq[ModuleID]）
5 、增加一个
dependency resolver
resolvers += "Repository name" at "http://the-repository/
releases"
增加本地maven repo
resolvers += "Local Mvn Repository" at
"file://"+Path.userHome.absolutePath+"/.m2/repository"
解决冲突
libraryDependencies += "slinky" % "slinky" % "2.1" from "http://slinky2.googlecode.com/svn/artifacts/2.1/ slinky.jar"
Sbt does not resolve dependencies with
classifier: https://github.com/harrah/xsbt/issues/285
intransitive() or notTransitive()比如：
libraryDependencies += "org.apache.felix" % "org.apache.felix.framework" % "1.8.0" intransitive()
libraryDependencies += "log4j" % "log4j" % "1.2.15" exclude("javax.jms", "jms")
ivyXML := <dependencies> <dependency org="javax.mail" name="mail" rev="1.4.2"> <exclude module="activation"/> </dependency> </dependencies>
5、发布
publishTo := Some("Scala Tools Nexus" at "http://mydomain.org/content/repositories/releases/")
>publish
credentials += Credentials(Path.userHome / ".ivy2" / ".credentials")
6、修发settings
:= 替换
+= 增加一个值
++=增加多个值
~=转换一个现有值 name ~= { _.toUpperCase }
修改靠依赖的有 <<= eg.
organization <<= name(_.toUpperCase)
name <<= (name, version)( _ + "-" + _ )
<+=
cleanFiles <+= (name) { n => file(.) / (n + ".log") }
watchSources <+= (baseDirectory, name) map{(dir, n) =>
dir / "conf" / (n + ".properties")
}
7.定义个task
val time = TaskKey[Date]("time", "returns current
time")
lazy val root = Project("test", file(".")).settings(
time := {
val now = new Date()
println("%s".format(now))
now
})
> time
8、sbt api
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
其它
启动 http://www.scala-sbt.org/release/docs/Detailed-Topics/Launcher.html
http://harrah.github.io/xsbt/latest/api/#sbt.SettingKey
To test some build code snippets in a scala REPL(this will load all build dependencies):
console-project
We can load build definition project with():
reload plugins
and go back to project with():
reload return
project definition: /build.sbt和 project/Build.scala
build definition :project/plugins.sbt和project/project/Build.scala
Inspect Settings - general informations:
inspect compile
Transforming a value: ~= 过滤自己
Computing a value based on other keys' values: <<= 靠别人改变自己（给别人起了个别名）
+= will append a single element to the sequence.
++= will concatenate another sequence.
Appending with dependencies: <+= and <++=
< Initialize[Id[V]] 参考其它值（依赖）(<<= ) <+=(< 的意思与+的组合)
+ 单个值增加 Seq[T] (+=)
++ 多个值增加到 Seq[T] (++=)
def ++=
[U](values: ⇒ U)(implicit a: Values[T, U]): Setting[Id[T]]
def +=
[U](value: ⇒ U)(implicit a: Value[T, U]): Setting[Id[T]]
final def :=
(value: ⇒ T): Setting[T]
def <++=
[V](values: Initialize[Id[V]])(implicit a: Values[T, V]): Setting[Id[T]]
def <+=
[V](value: Initialize[Id[V]])(implicit a: Value[T, V]): Setting[Id[T]]
final def <<= (app: Initialize[T]): Setting[T]
